Inner Rings for Shell Type Needle Roller Bearings IRT81210 IRT101420 IRT202520
Inner rings can be integrated with shell-type or various machined needle roller bearings to provide good roller support without worrying about premature shaft wear. We heat-treat and grind our inner rings to tight tolerances to create hard, tough raceways for applications where it is impossible to make shaft surfaces to a specific hardness or roughness attribute.
IRT Series
MOUETTE offers more interchange both standard and customized inner rings, in High-Alloy Bearing Quality Steel 100Cr6, and Stainless steel 440C.
